2022-10-05selftest: tpm2: Add Client.__del__() to close /dev/tpm* handleStefan Berger1-0/+4
The following output can bee seen when the test is executed: test_flush_context (tpm2_tests.SpaceTest) ... \ /usr/lib64/python3.6/unittest/case.py:605: ResourceWarning: \ unclosed file <_io.FileIO name='/dev/tpmrm0' mode='rb+' closefd=True> An instance of Client does not implicitly close /dev/tpm* handle, once it gets destroyed. Close the file handle in the class destructor Client.__del__().

2022-03-08selftests: tpm2: Determine available PCR bankStefan Berger2-8/+52
Determine an available PCR bank to be used by a test case by querying the capability TPM2_GET_CAP. The TPM2 returns TPML_PCR_SELECTIONS that contains an array of TPMS_PCR_SELECTIONs indicating available PCR banks and the bitmasks that show which PCRs are enabled in each bank. Collect the data in a dictionary. From the dictionary determine the PCR bank that has the PCRs enabled that the test needs. This avoids test failures with TPM2's that either to not have a SHA-1 bank or whose SHA-1 bank is disabled.

2020-06-29Revert "tpm: selftest: cleanup after unseal with wrong auth/policy test"Jarkko Sakkinen1-5/+0
The reverted commit illegitly uses tpm2-tools. External dependencies are absolutely forbidden from these tests. There is also the problem that clearing is not necessarily wanted behavior if the test/target computer is not used only solely for testing.

Unseal with wrong auth or wrong policy test affects DA lockout and eventually causes the tests to fail with: "ProtocolError: TPM_RC_LOCKOUT: rc=0x00000921" when the tests run multiple times.
